ABSTRACT:
In a linear motor having a rotor and a stator, the rotor comprises two rotor elements which can be clamped in the stator by means of clamping elements as a function in each case of a signal which is fed and which are connected by at least one piezoelectric element (actuator element) by which the distance apart of the rotor elements can be varied as a function of a control signal which is fed. By the application of an electric voltage there takes place in each case an expansion of the clamping elements transverse to the direction of movement and an expansion of the actuator element in the direction of movement. One particularly advantageous embodiment resides in the fact that the rotor is developed in a flat shape and that the rotor elements contain the clamping elements in a frame-like holder, at least one side of the frame-like holder being movable with respect to the other sides.
